Commercial  Fertilizers,  1926

THE  FERTILIZER  LAW. 

The  provisions  of  the  Connecticut  fertilizer  law  have  been  dis- 
cussed in  previous  reports  but  for  more  ready  reference  its 
essential  features  may  be  noted  here. 


Significance  of  the  Term  "Commercial  Fertilizers'"'' 

Explaining"  what  is  meant  by  the  term  "commercial  fertilizers" 
the  law  says : 

"The  term  'commercial  fertilizers'  shall  be  construed  to  mean  any  and 
every  substance  imported,  manufactured,  prepared  or  sold  for  fertilizing  or 
manuring  or  soil  amendment  purposes,  except  barnyard  manure  and  stable 
manure  which  have  not  been  artificially  treated  or  manipulated,  marl  and 
lime.  Cottonseed  meal,  rapeseed  meal,  castor  pomace  and  all  other  vege- 
table products  used  as  fertilizers,  including  the  ashes  of  cotton  hulls  and 
wood  ashes,  shall  be  included  as  fertilizers  within  the  meaning  of  this  act 
and  separate  analysis  fees  shall  be  paid  on  each  different  grade  which  is 
sold  or  offered  for  sale  in  the  state.  The  person  responsible  for  paying  the 
fees  above  prescribed  may  deduct  from  the  total  tonnage  sold  such  sales  of 
cottonseed  meal  or  other  vegetable  products  as  are  made  to  anyone  who 
gives  a  written  certificate  on  a  form  supplied  by  the  Connecticut  Agricul- 
tural Experiment  Station  stating  that  the  material  bought  by  him  was  to 
be  used  exclusively  for  feed  and  not  for  fertilizer." 

Concerning  Cottonseed  Meal. 

Cottonseed  meal  is  a  fertilizer  within  the  meaning  of  the  Statute 
but  it  is  provided  that  when  this  product  is  sold  for  feeding 
purposes  only,  it  shall  be  exempt  from  the  tonnage  tax. 

The  status  of  cottonseed  meal  under  the  fertilizer  law  has  been 
clearly  stated  in  a  bulletin1  from  this  Station  from  which  the 
following  may  be  quoted  : 

Registration  and  analysis  fees.  "Each  brand  of  cottonseed  meal  must  be 
registered  on  forms  provided  by  this  Station  and  an  analysis  fee  of  ten 
dollars  paid  on  it  before  it  is  sold,  offered  or  exposed  for  sale,  and  on  the 
first  day  of  January  annually  thereafter." 


1  Bull,  of  Information  No.  9,  1919. 


4  CONNECTICUT    EXPERIMENT    STATION  BULLETIN    282 

"A  distinctive  name  constitutes  a  distinct  brand.  If  shipments  have 
different  guaranties  of  composition  they  are  held  to  be  different  brands." 

Branding  or  tagging.  "Since  nitrogen  is  the  only  fertilizer  ingredient 
considered  in  the  trade  in  cottonseed  meal  no  guaranty  of  phosphoric  acid 
or  potash  is  required.  If  either  is  guaranteed  by  the  manufacturer,  how- 
ever, an  additional  fee  of  ten  dollars  must  be  paid  on  each  element.  The 
statement  of  composition  now  legal  for  feeds  may  be  used  hereafter  if  the 
percentage  of  nitrogen  is  stated. 

"Note  that  the  law  regarding  feeding  stuffs  forbids  the  use  of  metal  in 
attaching  tags  and  requires  that  each  package  shall  be  branded  or  tagged 
with  the  statement  required  by  law." 

Duties  of  shippers.  "It  is  assumed  from  correspondence  with  shippers 
outside  the  state  that  they  will  register  the  brands  which  they  sell  in 
Connecticut,  will  pay  analysis  fees  as  has  been  done  in  the  past  by  manu- 
facturers of  commercial  fertilizers,  and  will  semi-annually  thereafter  pay 
the  tonnage  fees. 

"They  will  report  to  this  Station  their  total  sales  and  if  they  wish,  may 
report  what  part  has  been  sold  for  feed  exclusively.  From  the  reports  of 
dealers  within  the  state  it  will  be  possible  to  determine  quite  closely  the 
amounts  of  each  brand  actually  used  as  feed. 

"In  the  case  the  jobber  outside  the  state  neglects  or  refuses  to  register  a 
brand,  the  dealer  who  sells  it  within  the  state  is  responsible  under  the  law." 

Duties  of  dealers.  "Dealers  are  required  to  file  with  the  director  of  the 
Station  on  July  first  of  each  year  and  semi-annually  thereafter  a  sworn 
statement  of  their  total  sales  of  each  brand  of  cottonseed  meal  and  the 
amount  of  each  sold  exclusively  for  feed,  during  the  preceding  six  months." 


Requirements  to  be  Complied  with  by  Sellers  of  Commer- 
cial Fertilizers. 

The  seller  is  responsible  for  the  proper  labeling-  of  each  pack- 
age, for  the  registration  at  the  Station  of  every  brand  sold  by  him 
and  for  the  payment  of  the  analysis  fee,  before  offering  for  sale, 
and  annually  thereafter  on  January  ist. 

The  law  specifies  the  information  which  shall  be  given  on  the 
label  as  follows : 

1.  Weight  of  each  package  in  pounds. 

2.  Brand  name  or  trade  mark. 

3.  Analysis : 

(a)  Available  phosphoric  acid,  per  cent. 

(b)  Total  phosphoric  acid,  per  cent. 

(c)  Nitrogen,  per  cent. 

(d)  Equivalent  ammonia,  per  cent. 

(e)  Potash  soluble  in  zvater,  per  cent. 

4.  Name  and  address  of  the  manufacturer  or  of  the  person 
who  is  responsible  for  the  statement  of  the  guaranty. 

In  the  case  of  bone  meal,  tankage  or  other  organic  products,  and 
in  basic  slag  and  mineral  phosphates  in  which  a  large  percentage 
of  the  phosphoric  acid  is  not  available  by  laboratory  methods,  the 


THE   FERTILIZER   LAW  5 

phosphoric  acid  shall  be  claimed  as  total  phosphoric  acid  unless 
it  is  desired  to  claim  available  phosphoric  acid  instead,  in  which 
case  the  guaranty  shall  take  the  form  set  forth  above. 

The  label  may  be  a  tag-  attached  to  the  package  or  a  statement 
printed  thereon.     Percentages  shall  be  minimum  percentages  only. 

The  presence  of  leather  in  its  various  forms,  wool  waste,  hair, 
or  any  inert  nitrogenous  material  shall  be  declared  on  the  label 
unless,  by  processing,  the  activity  of  these  materials  has  been 
rendered  satisfactory  as  determined  by  official  methods. 

When  potash  is  derived  from  sulphate  or  carbonate  of  potash 
it  may  be  so  claimed. 

No  claim  or  guaranty  for  less  than  0.82  per  cent  of  nitrogen  or 
for  less  than  I  per  cent  of  phosphoric  acid,  or  for  less  than  1  per 
cent  of  potash  shall  be  regarded  in  the  registration  or  analysis  of 
any  commercial  fertilizer. 

The  seller  must  also,  on  the  1st  of  January  and  July,  report 
the  tonnage  of  fertilizer  sold  within  the  preceding  six  months  and 
pay  to  the  director  of  the  Station  a  tonnage  fee  of  6  cents  per  ton. 

On  request,  copies  of  the  law  and  blanks  for  registration  and 
for  tonnage  reports  will  be  supplied  by  the  Station. 

If,  however,  proper  labeling,  registration  and  payments  have 
been  provided  for  by  the  manufacturer  of  the  brands  or  by  another 
responsible  person  all  sellers  of  such  brands  arc  released  from  the 
above  mentioned  requirements.  The  retailer,  therefore,  should 
assure  himself  that  the  requirements  of  the  law  have  been  met  by 
the  manufacturers  of  the  brands  which  he  handles,  or  himself  be 
prepared  to  meettall  these  requirements. 


Precautions  to  be  Observed  ix  Drawixg  Samples  for 
Analysis. 

The  analysis  of  a  fertilizer  is  of  no  value  unless  the  sample 
analyzed  represents  as  nearly  as  possible  the  stock  from  which  the 
sample  was  drawn.  The  law  prescribes  the  procedure  to  be 
followed  by  authorized  agents  of  this  Station  when  taking  official 
samples  for  analysis  as  follows : 

"When  samples  are  taken  from  fertilizers  in  bags,  a  tube  shall  be  used, 
and  it  shall  be  inserted  at  one  end  of  the  bag  and  shall  pass  substantially 
the  entire  length  of  the  bag,  so  as  to  take  a  core  of  the  material  being 
sampled  from  substantially  the  entire  length  of  the  bag.  Samples  thus 
taken  from  individual  bags  shall  be  thoroughly  mixed,  and  the  official 
samples  shall  be  taken'  from  the  mixture  so  drawn  by  the  method  known 
as  'quartering.'  Samples  of  fertilizers  taken  as  herein  provided  shall  be 
taken  from  at  least  five  per  centum  of  the  separate  original  unopened 
packages  in  the  lot,  for  the  mixture  from  which  the  official  samples  shall 
be  taken.  If  less  than  one  hundred  bags  are  in  the  lot,  at  least  five  bags 
shall  be  sampled;  if  less  than  five  bags,  all  shall  be  sampled.  Broken 
packages  shall  not  be  sampled." 


CONNECTICUT   EXPERIMENT    STATION  BULLETIN    282 


Gratuitous  Analyses. 

Under  the  fertilizer  law  the  Station  is  charged  only  with  the 
analysis  of  samples  drawn  by  its  own  agents.  It  does,  however, 
each  year  analyze  a  considerable  number  of  samples  drawn  by 
individuals,  representing  stock  purchased  by  them  for  their  own 
use.  The  object  of  the  purchaser  is  to  satisfy  himself  as  to 
whether  he  has  obtained  goods  of  the  grade  represented  and, 
perhaps,  to  obtain  evidence  upon  which  to  base  a  claim  for  short- 
age should  the  materials  not  meet  their  guaranties.  The  Station 
assumes  no  responsibility  for  the  sampling  in  case  of  such  un- 
official samples  and  can  only  vouch  for  the  accuracy  of  the  results 
obtained  on  the  materials  as  submitted.  Since  a  representative 
sample  is  as  essential  as  an  accurate  analysis  in  judging  the  quality 
of  a  shipment  of  fertilizer,  it  is  evident  that  a  satisfactory  adjust- 
ment will  seldom  be  effected  on  the  basis  Of  an  unofficial  sample. 
Notwithstanding  certain  objections  which  may  be  raised  to  the 
practice  of  analyzing  samples  submitted  by  individuals,  the  Station 
is  disposed  to  continue  such  work  so  long  as  there  is  evidence  that 
it  constitutes  a  useful  service;  it  cannot,  however,  undertake  for 
any  one  individual  or  group,  work  in  such  volume  or  with  such 
frequency  that  it  becomes  a  systematic  control  over  current 
purchases.  This  clearly  invades  the  field  of  the  commercial 
laboratory.

INSPECTION  OF  1926. 

During  the  year  the  Station  inspector  has  visited  86  towns  and 
villages  in  the  State  and  drawn  540  official  samples,  representing 
all  the  registered  brands  which  were  found  on  sale.  These  to- 
gether with  samples  submitted  by  purchasers,  or  others  interested, 
may  be  classified  as  follows  :

1 8  CONNECTICUT    EXPERIMENT    STATION  BULLETIN    282 

I.     RAW  MATERIALS  CHIEFLY  VALUABLE  FOR 
NITROGEN. 

NITRATE  OF  SODA. 

Nitrate  of  Soda  is  obtained  from  the  west  coast  of  South 
America,  chiefly  in  Chili.  Commercial  grades  of  the  salt  contain 
from  91  to  97  per  cent  of  sodium  nitrate  equivalent  to  from  15 
to  16  per  cent  of  nitrogen. 

Thirty-one  samples,  twenty-three  of  which  were  drawn  officially 
by  the  Station,  were  examined.  Twenty-nine  equalled  or  exceeded 
their  guaranties.  Sample  3812  showed  the  only  notable  deficiency, 
but  a  second  sample  from  another  source  was  not  deficient. 

Prices,  based  upon  ten  quotations,  have  ranged  from  $64.00  to 
$85.00  per  ton,  the  average  being  about  $72.00.  Nitrogen  from 
this  source  has  cost  on  an  average  about  24  cents  per  pound. 

Analyses  are  given  in  Table  I. 

OTHER  CONCENTRATED  AMMONIATES. 

There  is  an  increasing  interest,  both  011  the  part  of  manu- 
facturers and  growers,  in  some  of  the  newer  raw  materials  which 
supply  nitrogen  in  concentrated  form.  Field  experience  with 
some  of  these  products  is  limited,  but  so  far  as  they  have  been 
tried  in  this  State  and  elsewhere  they  have  produced  generally 
good  results.  Director  Slate  has  recently  discussed1  some  of  these 
newer  ammoniates. 

Calcium  Cyanamide.  This  is  an  air-nitrogen  product  which 
has  been  manufactured  in  this  country  for  some  years,  and  is 
relatively  cheap.  The  Muscle  Shoals  plant  is  designed  to  produce 
it.  The  commercial  article  usually  contains  20  to  25  per  cent  of 
nitrogen,  equivalent  to  25  to  30  per  cent  of  ammonia.  For  fer- 
tilizer purposes  this  form  of  nitrogen  is  regarded  as  of  organic 
nature.  It  is  rather  slowly  available  in  the  soil  and  should  be 
applied  some  time  before  planting  seed.  It  cannot  be  used  in 
large  quantity  in  mixed  goods  containing  acid  phosphate. 

Ammonium  Nitrate.  This  salt,  formerly  made  from  nitric  acid 
and  ammonia,  is  now  made  more  cheaply  in  Europe  from  air  nitro- 
gen. The  commercial  article  contains  about  41  per  cent  of  am- 
monia. It  leaves  no  residue  in  the  soil  and  has  given  good  results 
on  crops  so  far  as  it  has  been  tried.  It  tends  to  become  moist 
on  storage. 

Ammonium  Chloride.  (Muriate  of  Ammonia.)  This  salt 
contains  about  26  per  cent  of  nitrogen  equivalent  to  about  31 
per  cent  of  ammonia.     It  is  seldom  used  in  fertilizers  because  of

NITRATE   OF   SODA  1 9 

its  relatively  high  cost.  It  is  being  used  to  some  extent  in  Europe, 
however,  for  such  purpose. 

Urea.  This  is  a  recent  commercial  product  and  is  the  most 
concentrated  of  the  newer  ammoniates.  It  contains  about  45  per 
cent  of  nitrogen,  equivalent  to  55  per  cent  of  ammonia,  and  is 
made  by  a  new  process  directly  from  ammonia  and  carbon  dioxide. 
It  leaves  no  residue  in  the  soil  and  equals  nitrate  of  soda  in  avail- 
ability. 

"Leuna"  Saltpeter.  This  is  a  double  salt,  ammonium  sulphate- 
nitrate,  containing  26  per  cent  of  nitrogen  of  which  about  *4  is 
nitrate  nitrogen  and  24  is  ammonia  nitrogen.  It  is  hygroscopic 
but  a  product  claimed  to  be  drillable  is  being  offered. 

Other  raw  materials  which  supply  both  nitrogen  and  phos- 
phoric acid  are  being  offered.  Of  these  may  be  mentioned  the 
following : 

Ammonium  Phosphate.  (Ammo-Phos.)  This  salt  is  being 
produced  in  this  country  and  contains  about  14  per  cent  of  am- 
monia and  45  per  cent  of  phosphoric  acid.  It  has  given  good 
results  as  a  fertilizer  Avhere  tried. 

Urea  Phosphate.  It  contains  21  per 'cent  of  ammonia  and  45 
per  cent  of  phosphoric  acid.  Its  physical  condition  is  satisfactory 
and,  so  far  as  tried,  has  given  good  results  in  the  field.

CASTOR  POMACE. 

Castor  pomace  is  the  residue  left  after  removing  the  oil  from 
the  castor  bean.  It  is  poisonous  to  stock  and  should  be  kept 
away  from  farm  animals.  It  is  chiefly  valuable  in  fertilizer  mix- 
tures as  a  source  of  nitrogen  but  contains  also  about  one  per  cent 
of  potash  and  two  per  cent  of  phosphoric  acid. 

Forty-four  samples  were  analyzed  and  in  only  three  instances 
were  there  any  considerable  deficiencies  in  nitrogen,  these  being 
0.17,  0.27  and  0.37  per  cent. 

Generally  this  material  is  sold  on  a  guaranty  of  about  4.50  per 
cent  nitrogen  equivalent  to  5.50  per  cent  of  ammonia. 

The  average  nitrogen  content  found  this  year  is  about  5.1  per 
cent.     Last  year  it  was  4.75  per  cent. 

Prices  have  ranged  from  $23.00  to  $30.00  per  ton  and  averaged 
$26.00.  If  allowance  is  made  for  the  phosphoric  acid  and  potash 
present,  nitrogen  in  this  material  has  cost  23.2  cents  per  pound. 

Analyses  are  given  in  Table  III.

COTTONSEED  MEAL. 

One  hundred  and  thirty- four  samples  of  cottonseed  meal  have 
been  examined.  This  number  includes  official  samples  and  those 
submitted  by  purchasers. 

The  classification  of  samples  and  the  average  nitrogen  found  in 
each  group  are  given  in  the  following  summary : 

Average 
No.  of  Nitrogen. 

Grade  Samples.  % 

36  per  cent  protein  (5.76  N)  15  5.84 

41  per  cent  protein  (6.58  N)  68  6.60 

43  per  cent  protein  (6.88  N)  39  6.78 

Odd  per  cent 1 

No   guaranty    11  6.64 

Of  one  hundred  and  twenty-three  samples  with  guaranties 
given,  ninety-four  exceeded,  or  substantially  met,  such  guaranties 
and  twenty-nine  did  not.  In  the  43  per  cent  protein  group  the 
guaranty  of  6.88  per  cent  nitrogen  was  not  maintained  on  an 
average. 

The  range  in  price  based  upon  57  quotations  has  been  from 
$33.50  to  $46.00  per  ton  and  the  average  about  $41.00.  On  the 
basis  of  these  figures  nitrogen  from  this  source  has,  therefore,  cost 
about  31.2  cents  per  pound. 

Analyses  are  given  in  Table  IV. 


LINSEED  MEAL. 

Seven  samples  of  linseed  meal  were  analyzed.     All  fully  satis- 
fied their  guaranties. 

Analyses  are  given  in  Table  IV.

II.     RAW  MATERIALS  CHIEFLY  VALUABLE  FOR 
PHOSPHORIC  ACID. 

PRECIPITATED  BONE  PHOSPHATE. 

The  phosphorus  in  this  raw  material  is  nearly  all  in  the  so- 
called  "available"  form.  Precipitated  bone  phosphate  is  obtained 
as  a  by-product  in  the  manufacture  of  gelatin. 

Of  the  eight  samples  examined  all  exceeded  their  guaranties,  so 
far  as  guaranties  were  given,  with  the  exception  of  No.  3757.  In 
four  cases  no  guaranties  were  quoted  to  us,  but  the  samples  were 
of  good  quality. 

So  far  as  prices  were  quoted  available  phosphoric  acid  from 
this  source  has  cost  about  6.4  cents  per  pound. 

Analyses  are  given  in  Table  V.

ACID  PHOSPHATE. 

Acid  phosphate  is  the  chief  source  of  phosphoric  acid  in  mixed 
fertilizers.  It  is  obtained  by  treating  ground  phosphate  rock  with 
sulphuric  acid  which  results  in  the  formation  of  calcium  phos- 
phate of  the  soluble  mono-calcium  type  and  calcium  sulphate  or 
gypsum.  This  mixture  is  allowed  to  remain  in  a  tank  or  "hot 
bin"  where  it  solidifies  after  which  it  is  broken  up  and  ground  to 
a  suitable  condition  for  use  in  fertilizer  mixtures.  This  raw  mate- 
rial is  generally  guaranteed  to  contain  16  per  cent  of  available 
phosphoric  acid. 

Twenty-one  samples  were  analyzed  all  except  four  of  which 
equalled  or  exceeded  their  guaranties.  In  one  case  a  second 
sample  showed  no  deficiency. 

The  average  content  of  available  phosphoric  acid  is  16.4  per 
cent.  On  the  basis  of  the.  average  of  prices  quoted,  viz.,  $22.50, 
the  cost  of  available  phosphoric  acid  from  this  source  has  been 
about  6.9  cents  per  pound. 

Analyses  are  given  in  Table  VI.

POTASH    SALTS  37 

III.     RAW  MATERIALS  CHIEFLY  VALUABLE 
FOR  POTASH. 

The  potash  ingredient  of  mixed  fertilizers  is  supplied  chiefly  in 
the  forms  of  muriate  (chloride)  and  of  sulphate,  but  the  carbonate 
and  nitrate  are  also  used.  Tobacco  growers  in  the  New  England 
States  prefer  their  potash  supply  in  the  form  of  carbonate  or 
sulphate. 

Potash  salts  are  furnished  chiefly  from  German  and  French 
sources,  but  high  grade  muriate  is  now  produced  in  California 
and  Utah. 

CARBONATE  OF  POTASH. 

When  pure,  carbonate  of  potash  contains  68.2  per  cent  of  actual 
potash  (K20),  but  commercial  grades  usually  contain  from  60 
to  65  per  cent. 

The  eleven  samples  examined  this  year  all  contained  over  61 
per  cent,  the  range  being  from  61. 1  to  66.6  per  cent  and  the 
average  64.3  per  cent. 

Price  quotations  were  limited,  but  at  $125.00  per  ton,  which  was 
the  price  quoted  in  two  cases,  potash  from  this  source  has  cost 
about  9.7  cents  per  pound. 

Analyses  are  given  in  Table  VII. 

MURIATE  OF  POTASH. 

This  raw  material  as  obtained  in  commercial  grades  contains 
about  80  per  cent  potassium  chloride  which  is  equivalent  to  about 
50.5  per  cent  of  actual  potash  (K,0).  Guaranties  for  this  salt 
are  generally  placed  at  48  to  50  per  cent  potash. 

Twelve  samples  were  examined,  all  except  one  being  official 
samples  taken  by  the  station  agent.  All  samples  exceeded  48 
per  cent  of  potash  so  that  none  can  be  regarded  as  inferior.  How- 
ever, four  did  not  meet  the  guaranties  under  which  they  were 
sold.  In  one  of  these  cases  4603,  another  sample,  3924,  of  the 
same  goods  submitted  by  a  purchaser,  considerably  exceeded  the 
guaranty. 

Only  two  price  quotations  were  obtained  and  these  differed 
by  $16.00  per  ton.  The  average  potash  content  of  the  salts 
examined  is  50.4  per  cent  which,  on  the  basis  of  the  average  of 
quoted  prices,  makes  the  cost  of* potash  about  5.1  cents  per  pound. 

Analyses  are  given  in  Table  VII. 

SULPHATE  OF  POTASH. 

Commercial  grades  of  this  salt  contain  about  90  per  cent  of 
potassium  sulphate  equivalent  to  about  48  per  cent  of  potash 
(K20),  which  is  the  usual  guaranty. 


38  Connecticut  experiment  station  bulletin  282 

Ten  samples  were  examined  and  all  exceeded  48  per  cent  and 
met  higher  guaranties  where  such  were  made.  The  average 
potash  content  is  49.29  per  cent  and  the  cost  per  pound  has  been 
about  6.6  cents. 

Analyses  are  given  in  Table  VII. 

SULPHATE  OF  POTASH-MAGNESIA. 

Two  samples  of  this  material  were  found  to  be  of  normal  potash 
content  and  both  met  their  guaranties. 
Analyses  are  given  in  Table  VII. 

COTTON  HULL  ASHES. 

Cotton  hull  ashes  have  not  been  used  as  fertilizer  in  this  State 
to  any  considerable  extent  in  recent  years.  They  are  obtained 
from  the  South  where  the  hulls  are  used  for  fuel  purposes. 

They  are  variable  in  composition,  containing  from  10  to  40 
per  cent  or  more  of  potash,  2  to  12  per  cent  of  phosphoric  acid 
and  about  10  per  cent  each  of  lime  and  magnesia.  These  ashes 
are  free,  or  nearly  so,  from  chlorides  and  were  formerly  used  to 
a  considerable  extent  in  the  Connecticut  valley  for  growing 
tobacco. 

Three  samples  were  analyzed  this  year.  Two  of  them,  4069 
and  4173,  were  of  curious  and  unexplained  composition.  The 
potash  content  in  these  two  samples,  both  of  which  represented 
the  same  stock,  was  between  8.50  and  9.00  per  cent ;  they  con- 
tained about  30  per  cent  of  phosphoric  acid  and  4  and  11  per 
cent  of  lime  and  magnesia  respectively. 

Examination  of  the  stock  showed  the  material  to  consist  largely 
of  coarse  fused  masses  or  clinkers  which  were  very  high  in 
phosphoric  acid.  The  hulls  had  evidently  been  burned  in  such  a 
way  as  to  become  largely  mixed  with  phosphate. 

Sample  4886  from  a  later  shipment  was  of  normal  appearance 
and  potash  content. 

Analyses  are  given  in  Table  VII.

IV.    RAW  MATERIALS  CONTAINING  NITROGEN 
AND  POTASH. 

Six  samples  of  this  group  of  materials  have  been  examined, 
three  taken  by  the  station  agent  and  three  sent  by  purchasers. 

Analyses  are  given  in  Table  VIII. 

3762.  Nitrate  of  Soda  and  Potash.  Apothecaries  Hall  Co., 
Waterbury.     Sampled  by  station  agent  at  factory. 

4180.  Nitrate  of  Soda  and  Potash.  Apothecaries  Hall  Co., 
Waterbury.  Sampled  by  station  agent,  stock  of  Chas.  Cass, 
Wallingford. 

4181.  Nitrate  of  Soda  and  Potash.  Apothecaries  Hall  Co., 
Waterbury.     Sampled  by  station  agent  at  factory,  East  Windsor. 

4610.  Nitrate  of  Soda  and  Potash.  Apothecaries  Hall  Co., 
Waterbury.     Submitted  by  Apothecaries  Hall  Co. 

4489.  Nitrate  of  Soda  and  Potash.  Apothecaries  Hall  Co., 
Waterbury.     Submitted  by  Jas.  S.  Burroughs  Co.,  New  York. 

2688.  Nitrate  of  Potash.  Manufacturer  unknown,  stock  of 
J.  E.  Phelps,  Suffield.

The  five  samples  of  nitrate  of  potash  and  soda  represent  the 
same  orig'inal  stock.  This  stock  was  offered  by  Apothecaries 
Hall  Co..  Waterbury,  and  purchased  by  them  through  Jas.  S. 
Burroughs  Co.,  New  York.  It  was  sold  on  a  guaranty  of  12 
per  cent  potash  and  18  per  cent  ammonia. 

The  first  sample  taken  by  the  station  agent,  3762,  was  con- 
siderably deficient  in  potash.  Further  official  samples  taken  at 
the  warehouse  of  Apothecaries  Hall  Co.  and  from  the  stock  of  a 
purchaser  failed  to  substantiate  the  12  per  cent  guaranty  of  potash 
but  were  found  to  be  considerably  higher  in  potash  than  our  first 
sample.  Exchanges  of  samples  were  made  between  the  importers, 
the  dealer  and  the  Station  for  purposes  of  checking  results. 
Numbers  4181,  4610  and  4489  are  portions  of  one  official  sample. 
Number  4489  represents  the  portion  submitted  first  to  Jas.  S. 
Burroughs  Co.,  New  York,  who  afterwards  sent  us  a  subsample 
for  a  check  analysis.     Unfortunately,  the  package  was  damaged

in  transit  to  us  and  our  result  is  without  significance  so  far  as 
checking  the  analysis  made  for  the  importers  is  concerned.  Their 
result  for  potash  was  reported  to  us  at  12.88  per  cent. 

The  stock  in  question  was  rather  coarse  and  somewhat  lumpy, 
hence  sampling-  was  more  difficult  than  usual.  Our  first  result 
is  apparently  too  low  to  fairly  represent  these  goods;  but  there 
is  no  evidence  that  the  product  as  received  here  would  average 
as  much  as  12  per  cent  of  potash. 


V.     RAW  MATERIALS  CONTAINING  NITROGEN 

AND  PHOSPHORIC  ACID. 

DRY  GROUND  FISH. 

Non-edible  fish  such  as  menhaden  and  dogfish  and  the  offal 
from  fish  canneries  are  used  in  making  this  fertilizer  material. 
The  fish  is  steamed  and  pressed  to  remove  oil  and  afterwards 
dried  and  ground. 

Eighteen  samples,  ten  of  which  were  sampled  by  the  station 
agent,  were  analyzed. 

All  samples  equalled  or  exceeded  guaranties  for  phosphoric  acid 
and  all,  with  one  exception,  4635,  substantially  met  or  exceeded 
the  guaranties  for  nitrogen.  This  material  has  contained,  on  an 
average,  8.55  per  cent  of  nitrogen  and  6.92  per  cent  of  phosphoric 
acid.  At  the  price  quoted,  about  $70.00  per  ton,  and  allowing  4 
cents  per  pound  for  phosphoric  acid,  nitrogen  from  this  source 
has  cost  about  37.7  cents  per  pound. 

Analyses  are  given  in  Table  IX.

TANKAGE. 

The  material  sold  tinder  this  name  is  generally  bone  and  meat 
refuse  material  which  has  been  cooked  with  steam,  defatted  and 
dried.  The  analysis  depends  upon  the  relative  amounts  of  bone 
and  meat  in  the  product ;  tankage  containing  less  than  5  per  cent 
of  nitrogen  and  over  15  per  cent  of  phosphoric  acid  has  a  con- 
siderable admixture  of  bone.  High  grade  tankage  contains  8  to 
10  per  cent  of  nitrogen  and  from  5  to  10  per  cent  of  phosphoric 
acid. 

Garbage  tankage  is  obtained  by  processing  city  garbage  and  is 
of  less  value  as  a  fertilizer.  Such  material  will  usually  contain 
2-5  t°  3-5  Per  cent  °f  nitrogen  and  from  2  to  5  per  cent  of 
phosphoric  acid. 

Sixteen  samples  were  analyzed,  all  of  the  bone  and  meat  variety. 
Samples  4237,  3783  and  4120  did  not  meet  guaranties  for  nitrogen, 
while  one  sample,  3745,  was  deficient  in  phosphoric  acid. 

Analyses  are  given  in  Table  X. 


GROUND  BONE. 

Thirty  samples  of  ground  bone  or  bone  meal,  twenty-one  of 
which  were  sampled  by  the  station  agent,  were  analyzed. 

All  of  the  guaranties  for  phosphoric  acid  were  met  but  samples 
4477,  4484,  3793  and  4574  did  not  meet  their  guaranties  for 
nitrogen. 

Analyses  are  given  in  Table  XL

VI.     MIXED  FERTILIZERS. 

MIXTURES  CONTAINING  ONLY  NITROGEN  AND 
PHOSPHORIC  ACID. 

Three  samples  of  this  group  of  materials  were  analyzed. 

3758.  Ammo  Phos.  American  Cyanamid  Co.,  New  York. 
Sampled  by  the  station  agent  from  stock  of  Olds  &  Whipple,  Inc., 
Hartford,  Conn. 

4536.  Shoemaker's  "Swift-Sure"  Tobacco  Starter.  M.  L. 
Shoemaker  &  Co.,  Philadelphia,  Penn.  Sampled  by  the  station 
agent  from  stock  of  F.  S.  Bidwell  Co.,  Windsor  Locks. 

4501.  O  &  W  High  Grade  Tobacco  Starter.  Olds  &  Whipple, 
Inc.,  Hartford,  Conn.  Sampled  by  the  station  agent  from  stock 
of  E.  O.  Gates,  Pine  Meadow.

Ammo  Phos  contains  no  organic  nitrogen.  The  quality  of  the 
organic  nitrogen  in  the  two  other  samples  was  satisfactory  as 
judged  by  the  usual  laboratory  methods. 


MIXTURES  CONTAINING  NITROGEN,  PHOSPHORIC  ACID 
AND'  POTASH. 

Analyses  of  two  hundred  and  forty-seven  official  samples  of 
complete  fertilizers,  and  of  six  samples  submitted  by  purchasers 
or  others  interested,  are  given  in  Table  XII. 

In  this  table  the  "grade"  of  the  fertilizer  is  given  in  addition 
to  the  brand  name ;  and  in  the  analysis  the  items  of  ammonia, 
available  phosphoric  acid  and  potash  found  are  given  in  bold  face 
type  so  that  the  comparison  between  the  composition  claimed  and 
that  found  may  be  more  readily  seen.  A  brand  represented  as 
4-8-4,  for  example,  is  guaranteed  to  contain  not  less  than  4  per 
cent  of  ammonia,  not  less  than  8  per  cent  of  available  phosphoric 
acid  and  not  less  than  4  per  cent  of  potash. 

Some  of  the  conspicuous  facts  shown  by  the  inspection  this  year 
may  be  seen  in  the  following  summary: 


MIXED   FERTILIZERS  5X 

Total  number  of  official  samples  analyzed 247 

Samples  considerably  deficient  in 

one  item 69 

two  items    13 

three  items   1 

total    83 

Total  deficiencies   98 

Total  of  guaranties  made  (247  x  3) 741 

Samples  showing  deficiencies  in  money  value  greater  than  $1.00 
per  ton 11 

This  tabulated  statement  shows  that  about  1/t,  of  the  samples 
examined  have  failed  to  fully  satisfy  their  guaranties  in  all  of 
the  three  items  of  plant  food  guaranteed ;  that  of  the  total  number 
of  guaranties  made  (there  being  three  for  each  sample),  about  87 
per  cent  have  been  substantially  met  or  exceeded ;  that  considerable 
losses  in  money  value  (greater  than  $1.00  per  ton),  have  not  been 
involved,  excepting  eleven  samples  representing  only  about  4.5  per 
cent  of  the  total  number. 

These  data  are  in  close  accord  with  similar  calculations  made 
last  year.  One  sample  in  three  has  failed  to  meet  the  claim  in 
one  or  more  of  the  three  items  of  plant  food  guaranteed.  While 
many  of  these  shortages  are  relatively  small,  and  perhaps  within 
the  limit  of  reasonable  analytical  differences,  nevertheless  guaran- 
ties required  by  law  are  minimum  guaranties  and  they  ought  to 
be  met  in  all  cases. 

Concerning  Deficient  Samples. 

In  ten  samples  this  year  deficiencies  in  plant  food  have  exceeded 
$1.00  per  ton.1  In  some  cases  second  samples  have  not  been  found 
deficient  or  such  deficiencies  have  not  exceeded  the  above  value. 
In  other  cases,  however,  second  samples  could  not  be  secured.

3884.  Bartlett's  Green  Tree  Food.  Both  this  sample  and  a 
second  sample,  4126,  were  low  in  "available"  phosphoric  acid. 
The  manufacturer  explained  that  a  good  share  of  the  phosphorus 
used  was  derived  from  bone.  Since  the  conventional  method  for 
determining;  "available"  phosphoric  acid  does  not  apply  satis- 
factorily to  bone  and  tankage,  the  low  results  reported  may  be  thus 
explained. 

4539.  Royster's  5%  Truck  Guano.  This  sample  was  taken 
from  a  small  lot  of  six  bags.  The  analysis  shows  only  about  one- 
half  as  much  nitrogen  as  is  guaranteed  and  the  manufacturer 
raised  the  question  of  a  possible  mixture  with  other  goods  when 
our  sample  was  drawn.  We  are  unable  to  find  any  error  in  the 
identity  of  the  brand  or  in  the  sampling ;  and  our  analytical  results 
have  been  checked  by  ourselves  and  substantially  confirmed  by  the 
manufacturer.  It  is  unfortunate,  however,  that  other  shipments 
of  this  brand  could  not  be  located  and  further  analyses  made. 

4510.  Piedmont-Mt.  Airy  Guano  Co.,  Harvest  Brand  4-6-10. 
This  sample  showed  a  deficiency  of  2.5  per  cent  in  potash. 

4023.  I.  P.  Thomas  &  Sons  Economy  Fertilizer.  This  sam- 
ple was  1.49  per  cent  below  guaranty  in  available  phosphoric 
acid.  If  the  phosphorus  was  derived  from  bone  the  explanation 
already  given  for  No.  3884  applies  here. 

4058,  4293.  Wilcox  Potato  and  Vegetable  Phosphate,  4-8-6. 
Both  samples  were  deficient  in  potash. 

4178,  4453  and  4754.  Sanderson's  Atlantic  Coast  Bone  Fish  and 
Potash.  These  three  samples  were  all  low  in  available  phosphoric 
acid  but  all  represented  the  same  stock.  Another  sample,  4416, 
from  a  different  source  was  not  deficient.  Phosphoric  acid  in  this 
mixture  is  derived  from  bone. 


Commercial  Deficiencies  for  a  Period  of  Years. 

In  a  system  of  inspection  where  many  brands  are  represented 
by  a  single  analysis  the  products  of  the  several  manufacturers 
may  not  be  fairly  evaluated  in  any  one  year.  Although  it  is  our 
practice  to  examine  at  least  two  samples  of  any  brand  showing 
considerable  deficiencies,  a  second  sample  is  not  alway  obtainable. 
Comparisons  are  more  informing,  therefore,  if  made  upon  data 
covering  a  period  of  years.  A  number  of  different  bases  might 
be  chosen  for  such  comparisons,  but  since  it  has  been  our  practice 
for  many  years  to  cite  brands  in  which  commercial  deficiencies 
amount  to  one  dollar  or  more  per  ton.  these  data  have  been  com- 
piled for  the  6-year  period  192 1- 1926,  and  are  tabulated  in  Table 
XIV.  No  manufacturer  is  included  unless  ten  or  more  samples 
have  been  analyzed  in  the  period  covered.  The  compilation  shows 
that  of  a  total  of  about  1500  samples  analyzed  less  than  10  per 
cent  have  fallen  short  of  guaranties  to  any  considerable  extent 


MIXED    FERTILIZERS  53 

in  commercial  value.  Or,  in  other  words,  purchasers  have  received 
commercial  values  represented  by  the  guaranties  in  over  90  per 
cent  of  purchases  made.

Decrease  in  Proportion  of  Fertilizer  with  Low  Plant  Food  Content. 

In  a  previous  report1  it  has  been  pointed  out  that  nitrogen  costs 
two  to  three  times  as  much  in  low  grade  (1  per  cent  ammonia) 
fertilizers  as  in  high  grade  mixtures. 


1  Conn.  Exp.  Sta.,  Bull.  241,  p..  no,  1922. 


54  CONNECTICUT    EXPERIMENT   STATION  BULLETIN    282 

A  study  of  grades  with  reference  to  ammonia  content,  also 
cited  in  an  earlier  report,1  shows  that  in  the  period  1921  to  1924 
inclusive,  the  proportion  of  samples  containing  1  per  cent  of 
ammonia  decreased  from  10  per  cent  to  2  per  cent;  that  the  pro- 
portion containing  3  per  cent  or  less  of  ammonia  decreased  from 
54  per  cent  to  30  per  cent ;  and  that  the  proportion  containing  4 
per  cent  or  more  of  ammonia  increased  from  46  per  cent  to  70 
per  cent. 

At  the  Massachusetts  conference  of  the  Soil  Improvement 
Committee  it  was  recently  shown2  that  low  analysis  (less  than  14 
per  cent  of  total  plant  food)  mixtures  have  decreased  both  in 
number  and  tonnage.  Thus,  in  1922  there  were  29  low  analysis 
mixtures  in  Massachusetts  representing  a  tonnage  of  about  8000 ; 
in  1925  there  were  only  9  such  mixtures  representing  a  tonnage 
of  less  than  2100.  It  was  also  shown  that  of  the  total  registra- 
tions in  New  England  in  1925,  784  were  high  analysis  (14  per 
cent  or  over)  brands  and  126  were  brands  containing  less  than 
14  per  cent  of  plant  food.  On  an  average,  low  analysis  brands 
comprised  about  14  per  cent  of  total  registrations  in  New  England, 
varying  in  the  several  States  from  1/10  to  1/5  of  their  total 
registrations. 


New  England  "Standard  Nine." 

Nine  standard  grades  have  been  recommended  for  use  in  New 
England.  The  experience  in  this  State  has  been  that  in  the  three 
years  following  the  proposal  of  these  nine  grades,  the  number  of 
samples  analyzed  which  corresponded  exactly  to  the  "standard 
nine"  comprised  in  1923,  32  per  cent;  in  1924,  36  per  cent;  and 
in  1925,  44  per  cent,  of  the  total.  During  the  year  just  passed  the 
proportion  is  44  per  cent.  The  data  show  an  increasing  number 
of  samples  each  year  excepting  the  last,  falling  in  the  selected 
grades,  but  the  proportion  is  still  less  than  ^2  of  the  total. 

Citing  Director  Haskell's  report  again  it  appears,  from  a  ton- 
nage standpoint,  that  in  the  four-year  period  1922-1925  inclusive, 
five,  of  the  "standard  nine,"  viz.,  4-8-4,  5-8-7,  5-4-5,  8-6-6,  and 
3-10-4,  have  maintained,  or  increased  in,  tonnage;  three  grades, 
viz.,  0-12-6,  2-12-4  and  3-10-6  serve  no  evident  necessity  judging 
from  tonnage  returns ;  and  one  grade,  4-8-6,  has  shown  a  marked 
decrease  in  tonnage.  Some  of  the  standard  grades  have,  more- 
over, been  outstripped  in  tonnage  by  closely  related  formulas,  such 
as  4-8-7,  3-8,-4,  and  3-8-6.  The  report  concludes  that  there  is 
apparent  need  of  revision  of  the  nine  grades  originally  proposed.

Quality  of  the  Insoluble  Organic  Nitrogen. 

The  present  accepted  methods  of  evaluating  the  insoluble  or- 
ganic nitrogen  in  fertilizer  materials  distinguishes  between  the 
better  and  the  poorer  forms  of  nitrogen.  Activity  values  below  50 
per  cent  by  the  alkaline  method  and  below  80  per  cent  by  the  neu- 
tral method  are  accepted  as  indicating  inferior  nitrogenous  mate- 
rial. Both  methods  should  be  applied  before  judgment  is  passed 
in  any  case. 

During  the  past  season  four  samples  have  shown  activity  values 
somewhat  less  than  those  mentioned,  but  in  all  of  them  the  water- 
soluble  nitrogen  practically  equalled  or  exceeded  the  guaranties 
of  total  nitrogen  and  the  samples  were  passed.

WOOD  ASHES. 

Twenty  samples  of  wood  ashes  were  analyzed.  With  the  excep- 
tion of  two  samples,  2648  and  2744,  which  were  very  inferior, 
probably  leached  ashes,  all  were  of  good  quality.  Excepting  the 
two  samples  mentioned,  water-soluble  potash  ranged  from  4.53 
per  cent  to  7.92  per  cent  and  averaged  6.23  per  cent.  Phosphoric 
acid  ranged  from  1.33  per  cent  to  2.78  per  cent.  Wood  ashes 
will  usually  contain  30  per  cent  or  more  of  lime.  The  prevailing 
price  has  been  $5.00  per  unit  of  potash.  Canada  is  practically  the 
only  source  of  the  commercial  wood  ashes  used  in  this  State. 

Analyses  are  given  in  Table  XVI.

SHEEP  MANURE,  ETC. 

Twelve  samples  of  sheep  and  other  farm  manures  were  ana- 
lyzed. There  were  no  considerable  deficiencies  except  in  3876 
which  contains  about  Y\  of  one  per  cent  less  than  the  guaranteed 
amount  of  potash. 

These  materials  will  contain,  on  an  average,  about  130  lbs.  of 
plant  food  per  ton,  but  they  have  additional  agricultural  value  as 
conditioners  and  as  suitable  culture  media  for  the  growth  of  soil 
bacteria. 

Analyses  are  given  in  Table  XVII. 


LIME. 
Sixteen  samples  of  liming  materials  have  been  analyzed  during 
the  year  for  purchasers  and  others  interested.     Results  are  given 
in  Table  XVIII. 

The  following  discussion  on  the  use  of  lime  for  soil  amendment 
purposes  should  be  of  interest  and  is  contributed  by  the  Depart- 
ment of  Soil  Research. 


The  Use  of  Lime  in  Adjusting  the  Soil  Reaction. 
M.  F.  Morgan,  Soil  Investigator. 

Ever  since  the  state  was  first  settled  a  few  farmers  have  given 
some  attention  to  the  problem  of  "sour  soils,"  and  some  form  of 
lime  has  occasionally  been  applied  to  certain  fields ;  but  the  prob- 
lem of  soil  acidity  was  not  keenly  felt  as  long  as  good  yields  of 
the  standard  crops,  such  as  timothy,  corn,  tobacco  and  potatoes, 
could  be  obtained  without  the  use  of  lime.  Excellent  growth  of 
such  crops  have  been  produced  with  heavy  applications  of  manure 
or  commercial  fertilizers  alone. 

In  recent  years  there  has  been  an  awakened  interest  in  the  soil 
reaction  and  its  proper  adjustment.  Alfalfa  and  other  legumes 
have  begun  to  receive  more  attention.  Vegetable  crops  are  becom- 
ing increasingly  important.  The  nature  of  certain  plant  diseases, 
such  as  potato  scab  and  the  black  root  rot  of  tobacco,  is  now  more 
accurately  known.  Under  such  conditions  it  becomes  imperative 
that  the  farmer  should  have  definite  knowledge  of  the  reaction 
of  his  soil  and  how  it  may  best  be  corrected  to  meet  the  demands 
of  the  particular  crops  in  which  he  is  most  interested. 

The  older  ideas  of  determining  whether  a  field  is  "sour"  from 
its  general  appearance  are  mostly  very  poor  "guess  work." 
Pastures  which  produce  practically  nothing  but  moss,  cinquefoil, 
everlasting,  broomsedge  or  poverty  grass  are  supposed  to  be  too 
acid  to  grow  anything  else.     When  one  fails  to  get  a  stand  of

grass,  and  red  sorrel  appears  in  the  mowing  lots,  then  the  soil  is 
thought  to  be  "sour."  Probably  these  diagnoses  are  correct,  but 
they  are  not  necessarily  so.  Many  wet  fields  in  limestone  regions 
"look  sour,"  but  actually  contain  an  abundance  of  lime.  A 
serious  phosphorus  deficiency  can  produce  the  characteristic  symp- 
toms of  acidity  as  shown  by  the  character  of  pasture  vegetation, 
and  several  pasture  fertilization  trials  in  this  state  have  shown 
that  in  limed  plots  without  other  treatment  the  type  of  growth  is 
unchanged.  Sorrel  thrives  luxuriantly  on  a  soil  which  has  been 
heavily  limed,  if  'for  any  reason  there  is  not  a  complete  stand  of 
grass  or  clover.  A  large  number  of  soil  tests  by  the  Soils  Depart- 
ment of  this  Station  have  shown  that  practically  every  field  in  the 
state  is  acid  to  some  degree,  unless  it  has  been  limed  recently. 
Except  for  a  few  small  areas  in  the  western  part  of  the  state  the 
rocks  from  which  our  soils  are  derived  contain  no  lime  carbonate, 
and  even  in  these  areas  the  limestone  is  so  local  in  occurrence  as 
to  influence  the  soil  to  a  very  slight  extent.  Our  common  rocks, 
when  weathered  under  conditions  of  normal  rainfall,  normally 
produce  acid  soils.  The  degree  of  acidity  will  be  determined  by 
the  exact  nature  of  the  rock  from  which  the  soil  is  derived,  the 
climate,  the  leachiness  of  the  soil,  the  amount  of  organic  matter 
and  colloidal  material  (very  fine  particles)  which  the  soil  contains, 
and  the  agricultural  practice  followed  on  the  field.  All  farmed 
soils  of  humid  regions  tend  to  become  more  and  more  acid,  due 
to  the  constant  removal  of  basic  material  through  leaching  and 
crops  taken  from  the  field. 

The  true  measure  of  the  degree  of  soil  acidity  is  the  concentra- 
tion of  the  acid-reacting  matter  technically  known  as  "hydrogen- 
ions."  To  express  this  in  a  simple  way,  scientists  have  devised 
the  "pH"  scale.  On  this  basis,  a  neutral  soil,  neither  acid  or 
alkaline,  has  a  reaction  of  7  pH.  (The  figure  7  has  a  definite 
mathematical  significance  as  related  to  the  actual  concentration  of 
hydrogen-ions.)  Below  7  pH  indicates  acidity,  above  7  indicates 
alkaline  conditions.  As  applied  to  Connecticut  soils,  the  scale 
operates  as  follows : 

'  Below  4  pH,  extremely  acid  soils  of  rare  occurrence. 

4-5  pH — Very  acid  soils. 

5-6  pH — Moderately  acid  soils,  growing  good  crops  of  corn, 
timothy,  tobacco,  potatoes,  etc.,  when  other  condi- 
tions of  fertility  are  favorable,  but  too  acid  for 
alfalfa,  beets,  cabbage,  onions,  cauliflower,  and  other 
"acid-sensitive"  crops. 

6-y  pH — Slightly  acid  soils,  favorable  for  growth  of  most 
crops. 
7  pH — Neutral  soils. 

7-8  pH — Slightly  alkaline  soils,  rare  in  this  state  unless 
heavily  limed  at  a  recent  date. 


MISCELLANEOUS    FERTILIZERS,    ETC.  ^5 

Fortunately  it  is  now  possible  by  rapid  field  or  laboratory  tests 
to  determine  quite  accurately  the  "pH"  of  a  soil,  so  that  the  exact 
conditions  of  soil  acidity  may  be  known,  and  after  taking  into 
proper  consideration  the  amount  of  organic  matter,  drainage  con- 
ditions and  fertilizer  treatment,  one  can  estimate  fairly  closely 
the  need  for  lime  of  a  particular  crop  on  that  soil. 

It  is  not  always  necessary  or  desirable  to  lime  a  soil  which  has 
been  found  to  be  acid.  Certain  crops,  such  as  strawberries,  are  not 
affected  by  soil  acidity,  while  corn,  potatoes  and  timothy  do  well 
on  moderately  acid  soils  (5-6  pH).  Recent  investigations  have 
shown  that  the  black  root  rot  of  tobacco  is  most  prevalent  on  soils 
which  are  neutral  or  only  slightly  acid  (5.9  to  7  pH).  Potato 
scab  is  prevented  by  a  moderate  degree  of  acidity  (below  5.6  pH). 
Lawn  experiments  at  the  Rhode  Island  Station  have  demonstrated 
that  "weedless"  lawns  of  the  finest  fine-leaved  grasses  are  best 
secured  on  fairly  acid  soils.  Soil  acidity  may  be  either  injurious, 
of  no  consequence,  or  beneficial,  depending  upon  what  we  wish  to 
grow. 

If  it  is  necessary  to  make  a  soil  less  acid  or  correct  the  acidity 
entirely  in  order  to  produce  certain  crops,  some  form  of  lime- 
bearing  material  must  be  incorporated  with  the  soil.  In  common 
♦practice,  tbree  liming  materials  are  used  :  burnt  lime  ("stone  lime" 
or  "quick  lime"),  hydrated  lime  ("slaked  lime")  and  ground 
limestone  (lime  carbonate). 

The  relationship  between  the  chemically  pure  forms  of  the 
above  materials  is  as  follows :  100  lbs.  of  ground  limestone  =  74 
lbs.  of  hydrated  lime  =  56  lbs.  burnt  lime.  None  of  these  mate- 
rials are  pure,  and  usually  there  is  more  or  less  of  the  correspond- 
ing forms  of  magnesium,  similar  in  value  to  lime. 

Commercial  liming  materials  are  judged  on  the  basis  of  actual 
lime  and  magnesia  (oxides  of  calcium  and  magnesium),  which 
they  contain,  and  upon  their  degree  of  fineness.  The  various 
products  are  quite  variable  in  composition,  but  in  general  they 
will  contain  mixed  oxides  about  as  follows :

The  rapidity  of  action  of  lime  in  the  soil  will  depend  upon  its

ground  sufficiently  fine  to  produce  relatively  quick  effect  without 
prohibitive  cost  of  grinding.     For  average  conditions,  a  medium

BULLETIN    282 


ground  lime  or  limestone  seems  to  be  the  most  desirable  com- 
mercial product.  A  reliable  authority  states  that  pulverized  lime- 
stone, all  of  which  will  pass  a  10  mesh  sieve,  70%  of  which  will 
pass  a  50  mesh  sieve,  and  50%  of  which  will  pass  a  100  mesh 
sieve,  should  give  excellent  results,  and  yet  be  cheap  enough  to 
make  its  use  worth  while.  In  Ohio  the  standard  required  by  law 
for  agricultural  ground  limestone  is  that  95%  of  the  material 
shall  pass  a  10  mesh  screen,  50%  shall  pass  a  50  mesh  screen, 
and  30%  shall  pass  a  100  mesh  screen.  If  immediate  results 
are  desired  in  the  use  of  a  moderate  amount  of  lime  for  a  special 
crop  of  high  money  value,  extreme  fineness  may  be  desirable, 
regardless  of  the  greatly  increased  cost. 

The  exact  amount  of  lime  to  be  applied  to  properly  adjust  the 
soil  reaction  is  not  easily  determined,  even  in  the  laboratory,  and 
only  general  recommendations  can  be  made.  The  following  are 
safe  quantities  which  should  give  good  results  on  average 
Connecticut  soils :

MISCELLANEOUS    FERTILIZERS,    ETC.  89 


MISCELLANEOUS. 

In  this  group  are  included  thirteen  samples  of  check  fertilizers 
in  the  cooperative  program  of  the  Royster  Guano  Co.,  and  thirty 
samples  of  check  cottonseed  meal  in  a  similar  program  of  the 
American  Oil  Chemists'  Society. 

Eighteen  other  samples  of  a  miscellaneous  character  have  been 
analyzed,  making  the  total  for  this  group  sixty-one.  ' 

3996.  Four  Seasons  Fertiliser.  This  product  is  apparently 
intended  for  greenhouse  use  although  it  is  recommended  for  lawns, 
golf  greens,  etc.  It  consists  largely  or  entirely  of  waste  cacao 
material,  chiefly  cacao  shells.  It  contains  2.3  per  cent  of  nitrogen, 
all  of  which  is  organic  and  largely  (1.9  per  cent)  insoluble  in 
water ;  about  1  per  cent  of  phosphoric  acid ;  and  2.2  per  cent  of 
water-soluble  potash.  One  ton  of  this  material,  therefore,  con- 
tains about  no  lbs.  of  plant  food,  46  lbs.  of  which  is  nitrogen, 
largely  in  insoluble  and  inactive  forms.  The  use  of  this  material 
as  a  conditioner  or  amendment  might  be  justified  if  it  could  be 
obtained  at  reasonable  cost.

At  average  commercial  valuations  of  nitrogen  and  phosphoric 
acid  the  plant  food  in  these  materials  is  worth  about  $25.00  per  ton. 
They  are  rather  inferior  as  guanos,  however,  since  they  are  poor 
in  nitrogen,  the  element  for  which  such  materials  are  chiefly  valu- 
able. Guanos  of  fair  quality  will  contain  from  5  to  8  per  cent  of 
nitrogen  while  good  guanos  will  contain  10  per  cent,  or  over,  of 
this  constituent. 

2636.  Rock  Bone,  submitted  by  C.  R.  Burr  and  Co.,  Inc., 
Manchester. 

This  was  rather  coarse  bone  containing  1.53  per  cent  of  nitrogen 
and  30.80  per  cent  of  phosphoric  acid. 

3349.  Horn  Shavings.  Griffin  Button  Co.,  Shelton.  This 
waste  material  contains  14.59  Per  cent  of  nitrogen  and  a  trace  of 
phosphoric  acid.  The  nitrogen  is  practically  all  insoluble  but 
activity  values  by  laboratory  methods  were  high,  80  to  90  per 
cent.  Some  authorities  regard  horn  as  inferior  because  of  its 
slow  decomposition;  others  regard  it  as  an  effective  fertilizer. 
On  the  basis  of  "activity"  values  for  nitrogen  by  present  methods 
it  cannot  be  regarded  as  inferior.

3659.  Bone  Meal  which  had  been  used  hardening  steel.  Sub- 
mitted by  E.  W.  Aspelin,  Bristol.  The  nitrogen  of  the  bone  had 
been  burned  away  but  the  material  contained  21.12  per  cent  of 
phosphoric  acid.  It  could  be  used  as  a  source  of  phosphorus 
for  fertilizer  purposes. 

3907.  Wool  Waste.  Submitted  by  the  Somersville  Mfg.  Co., 
Somersville.  Material  of  this  sort  may  contain  considerable  and 
varying  amounts  of  nitrogen  and  small  amounts  of  potash,  usually 
from  1  to  3  per  cent.  This  sample  contained  14.59  Per  cent  of 
nitrogen.  The  nitrogen  is  slowly  available,  however,  and  in  the 
fertilizer  industry  such  material  is  treated  with  sulphuric  acid 
which  makes  the  nitrogen  more  active.  After  this  treatment  it  is 
suitable  for  mixing  with  other  base  goods  in  commercial  fertilizer 
mixtures. 

Wool  waste  has  been  used  directly  on  the  farm,  spreading  it 
broadcast  and  plowing  under  in  preparation  for  seeding  down. 
It  can  also  be  utilized  in  compost  heaps  mixed  with  wet  stable 
manure.

Sample  3801,  as  received,  was  about  %  water,  so  that  3  tons 
would  yield  about  I  ton  of  air-dry  material  and  contain  about  60 
pounds  of  plant  food.  Sample  3929  was  about  ]A  water,  hence 
2  tons  would  yield  1  ton  of  air-dry  material  and  contain  about 
50  pounds  of  plant  food. 

In  addition  to  the  plant  food  contained  in  it  such  material  has 
some  value  as  a  conditioner  on  light  soils,  but  the  cost  of  carting, 
drying,  etc.,  is  likely  to  exceed  its  agricultural  worth. 

The  incinerator  ashes  are  poor  in  fertilizer  ingredients,  the 
phosphoric  acid  and  potash  in  them  being  worth  less  than  a  dollar 
per  ton.

3056.  "Black  Tobacco"  and  3057  Light  Tobacco.  Submitted 
by  Dr.  P.  J.  Anderson,  Tobacco  Station,  Windsor. 

In  the  curing  of  tobacco  "black"  leaves  sometimes  occur  which 
as  compared  with  normal  (light)  leaves  are  of  poor  quality  and 
of  little  commercial  value. 

Comparative  analyses  of  "black"  and  light  leaves  are  given  in 
Table  XIX. 

The  analyses  were  made  partly  because  of  the  fact  that  some 
growers  felt  that  the  occurrence  of  black  leaves  was  possibly  due 
to  the  increased  use  of  magnesia  in  their  fertilizer  materials. 
While  the  black  leaves  show  about  twice  as  much  magnesia  as 
the  light  leaves,  there  appears  to  be  no  special  significance  in  this 
since  old  analyses  show  considerably  larger  amounts  of  this  in- 
gredient than  was  found  in  either  of  these  samples.

THE  EFFECT  OF  CHLORIDES  UPON  THE  BURNING 
QUALITY  OF  TOBACCO.1 

E.  H.  Jenkins,  Director  Emeritus. 

Regarding  the  use  of  muriates  (chlorides)  as  tobacco  fertilizers 
the  opinion  and  practice  of  New  England  tobacco  growers  devel- 
oped probably  in  large  measure  from  the  account  of  the  experi- 
ments of  Nessler  and  others  in  Germany  which  was  set  forth  by 
Prof.  S.  W.  Johnson,  then  chemist  of  the  Connecticut  Board  of 
Agriculture,  in  the  report  of  the  Board,  1872,  p.  384.  He 
concluded : 

"It  is  a  result  of  observation  in  our  state  as  well  as  in  Europe  that 
the  use  of  salt  (muriates)  increases  the  crop,  but  with  detriment  to 
its  burning  quality. 

"We  must  in  general  avoid  employing  fertilizers  which  contain  salt 
or  other  chlorine  compounds  in  raising  wrapping  or  smoking  tobacco." 

At  the  same  time  Johnson  notes  that  chlorine  is  not  the  only 
cause  of  poor  burn. 

"It  is  most  probable  that  burning  quality  is  the  result  of  the  coinci- 
dence of  several  conditions. 


1  The  renewed  interest  in  the  question  of  chlorides  in  fertilizer  materials, 
and  the  proposed  limitations  for  chlorine  in  raw  materials  and  in  mixed 
goods  intended  for  use  in  tobacco  culture,  make  this  brief  review  by 
Dr.  Jenkins  of  particular  interest.     (E.  M.  B.) 


MISCELLANEOUS    FERTILIZERS,    ETC.  93 

"Abundance  of  organic  potash  in  the  leaf  (that  is  potash  combined 
with  organic  acids),  abundance  of  cellulose  (woody  fiber),  abundance 
of  sulphates,1  are  evidently  favorable  to  easy  burning  On  the  other 
hand,  sugar,  gum  (pectic  acid)  and  albuminous  matters  are  difficult 
of  combustion.  Mineral  salts,  which  fuse  at  a  burning  temperature, 
chlorides  and  phosphates  of  potash  and  soda,  hinder  free  burn." 

Fermentation,  which  reduces  the  quantity  of  sugar  and  prob- 
ably other  ingredients,  acts  on  the  whole  to  improve  burn.  The 
results  given  in  our  Bulletin  180,  however,  prove  that  in  no  case 
was  the  fire-holding  capacity  of  a  poor  burning  sort  made  satis- 
factory by  fermentation. 

Garner  observes  that  the  compounds  in  the  leaf  which  are  of 
importance  in  producing  a  good  burn  are  the  potash  salts  of  the 
organic  acids  such  as  malate  and  citrate,  and  these  are  only  formed 
from  the  potash  which  remains  over  after  the  mineral  radicals, 
such  as  chlorine  and  sulphuric  acid,  have  been  neutralized. 

While  the  harmful  effects  of  chlorine  under  certain  conditions 
is  everywhere  admitted,  the  question  has  been  raised  whether  the 
experiments  made  in  other  countries,  on  soils  different  from  ours, 
with  different  strains  of  tobacco  and  under  methods  of  growing 
and  harvesting  unlike  our  own,  were  strictly  applicable  to  our 
conditions ;  and  it  has  been  asked  what  definite  and  careful  tests 
have  been  made  in  this  country  which  prove  that  muriates  injure 
the  burning  quality  of  the  leaf.  It  is  worth  while  to  consider  the 
question  and  note  the  observations  of  different  experimenters. 

The  Virginia  Station2  reports  that  experiments  conducted  since 
1906  indicate  that   "The   sulphate  is   preferable  as   a   source  of 

potash  for  flue-cured  tobacco Muriate  and  kainit  contain 

chlorine ;  experiments  have  established  the  fact  that  chlorine  tends 
to  impair  the  burning  quality  of  the  leaf."  Fifty  to  one  hundred 
and  fifty  pounds  of  sulphate,  i.  e.,  25  to  75  pounds  of  potash,  are 
recommended. 

T.  K.  Wolfe,  Professor  of  Agronomy,  Virginia  Polytechnic 
Institute,  says  :3 

"Five  years  results  with  dark  tobacco  and  two  years  results  with 
light  tobacco  show  that  tobacco  produced  from  the  use  of  muriate 
was  equal  and  usually  superior  to  that  produced  from  the  use  of 
sulphate  of  potash.  The  selling  price  of  the  muriate  and  sulphate 
tobacco  was  identical.  From  the  standpoint  of  yield  and  selling  price 
muriate  of  potash  is  to  be  preferred  to  sulphate  especially  since  the 
former  is  cheaper.  In  tobacco,  the  burning  quality  has  to  be  considered 
as  well  as  the  yield.     Burning  tests4  conducted  with  tobacco  from  the 


1  Further  observation  make  more  than  questionable  the  value  of  "abund- 
ance of  sulphates."

94  CONNECTICUT    EXPERIMENT   STATION  BULLETIN    282 

Virginia  Station  showed  that  the  sulphate  of  potash  held  fire  for  3^ 
minutes  while  the  muriate  of  potash  held  fire  for  1%  minutes  or  exactly 
one-half  as  long  as  the  sulphate  tobacco." 

In  the  report  of  the  North  Carolina  Station,  1919,  p.  32,  it  is 
stated  that  while  there  is  some  evidence  that  muriate  may  give 
good  results,  from  the  standpoint  of  the  grower  its  use  is  not 
advocated  because  without  doubt  it  injures  the  burning  quality. 
In  the  experiments  as  high  as  160  pounds  of  potash  were  used  but 
from  36  to  40  pounds  pays  best. 

Practically  the  same  is  said  in  the  North  Carolina  report  for 
1920,  i.  e.,  muriate  in  quantities  up  to  80  pounds  per  acre  of  potash 
gave  larger  yields  but  poorer  quality. 

In  the  report  of  the  same  Station,  1921,  p.  30,  larger  yield  from 
muriate  is  reported  and  market  value  the  same  as  from  tobacco 
grown  on  sulphate,  but  muriate  does  not  improve  the  burning 
quality. 

A  letter  from  the  chemist  of  a  fertilizer  company  doing  a  large 
business  in  the  southern  tobacco  regions  says  that  the  Virginia 
and  North  Carolina  tobacco  regions  recommend  a  fertilizer  supply 
of  potash  of  one  half  muriate  and  one  half  sulphate  of  potash. 

The  Ohio  Station1  states,  in  experiments  with  tobacco  grown 
alone  or  in  rotation  with  other  crops,  but  with  the  fertilizers 
applied  on  tobacco,  covering  six,  five  and  four  year  periods,  60 
pounds  of  muriate  were  applied  per  acre.  When  the  amount  of 
muriate  was  increased  the  yield  was  not  increased  and  the  quality 
was  reduced. 

These  observations  were  made  in  regions  where  pipe  and  ciga- 
rette tobaccos  are  produced  and  where  "burn"  is  not  so  vital  a 
thing  as  with  us  where  wrapper  and  binder  leaf  is  the  only  kind 
grown  at  present. 

With  us  in  New  England  a  good  burn  is  about  the  first  essential. 
The  leaf  must  hold  fire  well,  not  burning  too  fast  or  too  slowly. 
It  must  not  coal  on  the  cigar  and  it  must  leave  a  clear  white  or 
light  gray — not  "muddy" — ash.  These  requirements  for  the  most 
part  do  not  apply  to  other  types  of  leaf.  Moreover,  the  quantity 
of  potash  used  at  the  south,  40  to  75  pounds  to  the  acre,  is  much 
less  than  is  used  here,  150  to  200  pounds — which  is  perhaps  in 
some  cases  excessive.  Under  our  conditions,  therefore,  it  is  evi- 
dent that  the  risk  of  damage  in  using  muriate  is  very  much  greater 
than  with  other  types  of  tobacco. 

At  the  same  time  some  growers  have  been  unnecessarily  anxious 
to  exclude  even  quite  small  quantities  from  the  fertilizer.  It  is 
certain  that  a  certain  small  quantity  is  necessary  to  the  normal 
development  of  the  crop.

MISCELLANEOUS    FERTILIZERS,    ETC.  95 

Dr.  Garner1  concludes  from  his  laboratory  tests  that  while  chlor- 
ine is  undoubtedly  injurious  the  experiments  indicate  "that  it 
requires  larger  quantities  to  seriously  affect  the  burning  quality 
than  is  commonly  supposed." 

Dr.  Anderson  of  the  Tobacco  Sub-Station  at  Windsor  kindly 
permits  the  following  statement  in  advance  of  his  printed  report. 

Plots  under  test,  each  made  in  triplicate,  had  identical  applica- 
tions of  nitrogen  and  phosphoric  acid.  All  received  the  same 
amount  of  actual  potash,  172  pounds  per  acre,  but  in  different 
forms.  From  each  set  of  three,  160  burning  tests2  were  made, 
after  fermentation,  with  these  results. 

Tobacco  fertilized  with  sulphate  of  potash  burned   34.3  sec. 

Tobacco  fertilized  with  carbonate  of  potash  burned  44.9  sec. 

Tobacco  fertilized  with  muriate  of  potash  burned  4.8  sec. 

Tobacco  fertilized  with  2/3  nitrate,  1/3  carbonate  burned  43.1  sec. 

Tobacco  fertilized  with  J4  sulphate,  J^  carbonate  burned 38     sec. 

Tobacco  fertilized  with  1/3  carbonate,  1/3  nitrate,  1/3  sulphate  . .  43-5  sec. 

Tobacco  experts  who  examined  the  leaves  also  agreed  that  the 
chlorine  (muriate)  sample  had  bad  burning  quality  and  that  all 
the  others  were  good.  Thus  the  evidence  of  experiment  and 
observation  of  intelligent  growers  indicate  that  to  use  any  con- 
siderable amount  of  muriate  of  potash  in  tobacco  fertilizers  is 
sure  to  damage  or  ruin  its  quality  but  no  damage  is  likely  to  be 
done  by  the  very  small  quantities  of  chlorine  unavoidably  present  in 
commonly  used  fertilizer  materials.  The  desire  of  some  growers 
to  exclude  even  these  small  quantities  is  not  justified.  Let  it  also 
be  borne  in  mind  that  poor  burn  may  also  be  caused  by  the  acci- 
dents of  the  season  and  is  not  always  to  be  ascribed  to  a  fault  in 
the  fertilizer.
